2. Cackling Goose

   Number observed:  3

   Details

   When workers canoed out to Pond 1 island around 7am, the Canada Geese and Snow Goose starting causing a ruckus and flushed. Shortly after the first wave of geese departed, a flock of five geese flew over us also heading SE towards Mason Park. This group of five included two Canadas and three Cacklers. The Cacklers were noticeably smaller than the Canadas, with proportionally small bills. More importantly, they were “hank”-ing rather than honking, higher pitched.
